Need Wolfram resources of David J Griffiths(3rd)' problem solution

As a physics undergraduate student, I am a freshman to quantum mechanics. Now, I want to learn quantum mechanics by Mathematica. Is there any video about using it to solve Griffiths’ problem?
My codes always go wrong, so I need relevant videos to help me.

I have not checked all notebooks, but it looks fine.

Note we also have Wolfram quantum framework: https://resources.wolframcloud.com/PacletRepository/resources/Wolfram/QuantumFramework/

Many examples in Griffiths’ book can be done in the Wolfram quantum framework now
